2. Nepalese Seasons Understanding
Nepal divides into 6 different climates periods, each lasting around 2 months.
- Hermanta Ritu (Early Winter): mid-November to mid-January);
- Shishir Ritu (Winter): mid-January to mid-March;
- Basanta Ritu (Spring): mid-March to mid-May;
- Grishma Ritu (Summer): mid-May to mid-July;
- Barkha Ritu (Monsoon Season): mid-July to mid-September;
- Sharad Ritu (Fall): mid-September to mid-November;
There are no exact dates for each season. It all depends on the Hindu Calendar.
Spring (Basanta Ritu): mid-March to mid-May
It’s the High Season and, for many backpackers, the best time to visit Nepal.
It is also a full season and when you get higher prices for Hotels and Tours.
The weather is delightful in the middle lands, scorching in the Terai region (South) and average, but windy, in higher altitudes.
It’s the second best good season for trekking. The weather is fairly good, maybe with some showers but, the haze is, probably, what makes this season less crowded with trekkers.
Summer (Grishma Ritu): mid-May to mid-July
It’s the hottest season in Nepal, with a scorching sun either in the south either the north.
It is also when the rainy period starts in Nepal, but it’s not a deterrent factor, that prevents tourists from traveling.
When you get there, if you need, buy an umbrella, and that’s enough.
It only rains for 1/2 hours every 2/3 days a week. And usually, happen at the end of the afternoon and mainly at night.
Despite the rain, the South is hotter than ever. The temperature can reach the 46ºC (114.8ºF). Avoid hostels without AC.
Monsoon Season (Barkha Ritu): mid-July to mid-September
The monsoon season in Nepal is not as intensive as in India and, for some people, a good opportunity to avoid the crowd.
The Tarai region, the South, is usually more affected, with unyielding showers, while the North has a more regular rain, especially in the Himalayas.
The streets are muddy, which makes traveling harder and more dangerous. In this season, don’t forget your umbrella. You will need it almost all the time.
It’s the cheaper period to visit Nepal and the best one to get in touch with local culture, away from the tourist flood.
Fall (Sharad Ritu): mid-September to mid-November
The weather starts to cool down from the summer’s burning sun, but also a pleasant relief from the monsoon season.
At the end of the monsoons, the sky is clear, and possible see the Himalayas from Pokhara or Kathmandu Valley.
With a clear view, an average temperature in all Nepal (not yet too cold), this is the best time to visit Nepal and trek in the Himalayas.
Early Winter (Hermanta Ritu): mid-November to mid-January)
The good cool weather starts to transform into a cold one. The Winter is settling down.
The skies are becoming clearer and the mountains with more snow, that eventually, starts to be harder to go to some higher places.
Winter (Shishir Ritu): mid-January to mid-March
While Nepal starts freezing, the skies become clearer. It’s ok for viewing the Himalayas from a distance, despite having some clouds, that will give the opportunity to take more dramatic photos
It is still ok for trekking, but snow or coldness won’t allow you to go above 3500 – 4000 meters (13,123 feet).
You should try the Jomoson Trek, near Pokhara, but don’t go above 3000 meters (9842.51 feet). Above that height, you can get heavy snow, and it could be dangerous.
To do that, better to prepare yourself, be fit and be aware that in the low-lying areas you should expect cold currents, so better to pack accordingly.
3. Is it possible to travel in Nepal during the monsoon season?
The answer is yes.
It might not be the best time to visit Nepal, but the monsoons there, don’t make traveling impossible.
It rains mostly in the evening and night time. You just need to buy an umbrella so survive the short rain moments but expect a lot of mud in the streets.
In the other hand, it’s a perfect time for photos, especially in the morning, when the sky becomes clear, and you can get a more dramatic view of the Himalayas.
4. What is the best time to visit Nepal
In the Spring, from March to May, is probably the best time to visit Nepal. Is the períod of the year when you’ll get the most reasonably good weather, but is also the most crowded and pricey.
If you are a trekker, better to choose the fall. The view is fantastic, and there is no better time to see and go to the Himalayas.
